IF you require bigger sheet of Fr4 or a sheet cut to size then please send us an email

We purchase 1220 x 915mm sheets and cut them down to size. We are not really geared up to dispatch sheets this size but can if required. Please call if you require this or a larger size than listed within our web store

450 x 600 mm Sized Sheets

The 450 x 600 sized sheets have to be dispatched using Parcel Force, as they are too large for Royal Mail. The only problem with this is the collection is at 3pm, so if you order after 2.00pm your order will get shipped the next day, and if ordered on a Friday that means you will not get your delivery until the following Tuesday as Parcel Force do not deliver over the weekend.

As we only use 1st Class post that means you should get it the next day, as long as your sheet size is pre-cut and in stock.

This is mainly due to the fact that they are easy to post within tough cardboard packets.

Other sheet sizes available upon request, bigger, smaller and other dimensions.

Sheet thickness tolerance up to +/- 10%. If thickness is vital, please contact us and we can measure the currant batch.

Our Fr4 / G10 in UNCLAD (it has no copper).

Our laminate material is a standard thermo-laminated glass epoxy material. It constructed from woven fiberglass cloth with a resin binder. The FR stands for flame retardant.

The colour is solid all the way through the material. So if you cut it the edge will be them same as the sheet colour.

If within our web shop you see low stock of a size, it does not mean we do not have a good stock of the larger sheets. You can always call us to check.

We offer discounts when purchasing more than 3 sheets of any one size and thickness. This is automatically applied at the check-out.

FR4 is used for most of out flat parts and assemblies.

FR4 and G10 are very similar materials, put side by side you would not be able to tell the difference. They have the same strength, weight and look the same. FR4 is Fire Retardant – G10 is not.

Although we may only show a relatively low number of small sheets available in stock, we hold a larger amount of FR4 in much larger sheet sizes. These are cut down as required, so if you wish to order a larger amount than that shown, its would not normally be a problem. You can also contact us beforehand if concerned.

All of our Fr4 sheets are classes as “industrial laminates” and not “cosmetic finished panels” so some sheets may have slight surface imperfections, though generally the surface finish is totally flat and imperfection free.

Should you require a bulk order we will ba able to offer you a discount

G10 / Fr4 VS carbon Fibre

G10 / Fr4 is heavier then Carbon of the same thickness

G10 / Fr4 Isn’t as stiff as Carbon of the same thickness

G10 / Fr4 Is Cheaper

G10 /Fr4 will not block radio / RF signal

G10 / Fr4 will flex more before it breaks

G10 / Fr4 doesn’t conduct electricity (something to consider also)

G10 / Fr4 according to knife makers the G10 /Fr4 scales feels and polishes up better

NOTE FR4 Thickness:- FR4 is manufactured to a tolerance with regards its thickness. If you require an exact thickness for a project please call before ordering. Thickness size can be +/-10% of the thickness listed in the main description.

However we normally find that the thickness is +/- 10%

This of course makes a greater difference the thicker you purchase. Other Companies do not list this detail, as many customers would be happy with an extra thickness. The governing standard is the International Electro-technical Commission (IEC) 60893-3-3 Technical Specification – Insulating Materials – Industrial rigid laminated sheets based on thermosetting resins for electrical purposes.

Strength Test G10 vs Carbon Fibre

This is not my video but one found on YouTube Here is the owners site if you are into knife building please take a looks he has loads of great videos htuffthumbz

In the video the G10 and carbon gets bashed with a large hammer, an axe, burnt, attacked with a large knife, put in a punch press and shot with a cross bow

Please note there are using G10 and NOT FR4. Fr4 is made with fire retardant resin so it will not burn like the G10 shown in the video

Warning – DUST:- If you are going to cut this product yourself ensure that your protect yourself against the dust that will be generated. We highly recommend that your wear a correctly rated half mask respirator. Protective respiratory masks comply to EN149:2001

Classification

This means that an FFP3 Respirator Mask would filter out at least 98% of the airborne repairable particles, whereas an FFP1 Respirator Mask would filter out at least 78% of the repairable particles. FFP3 Respirator Masks are therefore most efficient respiratory masks in filtering out fine particles including viruses, mould spores & asbestos. Therefore ensure that you purchase a good fitting FFP3 Mask.
